LAMP.

SPECIFICATION forming part of Letters Patent No. 788,994, dated May 2, 1905.

Application file July 20, 1904. Serial No. 217,378.

To all whom, it may concern.-

Be it known that I, ABRAHAM BLESHMAN, a subject of the Czar of Russia. residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Lamps, of which the following is a specification.

My invention relates to a protector for lamps, and particularly to lamps in which mantles of a delicate nature are used.

The object of my invention is to provide a hood or protector which will inclose the said mantles when the globe of the lamp is removed, so that said mantles will be protected from destruction by the wind.

A further object of my invention is to use said hood as a secondary casing to prevent the outer casing from being overheated when the lamp is burning.

Referring to the drawings, Figure 1 is a vertical sectional view of a lamp, showing my invention embodied therein. Fig. 2 is a view similar to Fig. 1, showing the hood in the lower position protecting the mantles and the globe of the lamp removed. Fig. 3 is a horizontal sectional view as on line 3 3, Fig. 2.

ln the drawings, A represents a central pipe, which carries the supply of gas to the burners B, having mantles B.

The lamp consists of a casing C, constructed in the usual form, which is supported upon the central pipe A by arms 0.

The hood D for protecting the mantles consists of a conical casing (Z, carried by arms globe is supported upon the central pipe A by a bracket E. When it is desired to remove the globe to clean the lamp, the bracket E is loosened and the globe is lowered and removed from the lower end of the central pipe A. As the globe is lowered the hood D, being loosely mounted upon the central pipe A, will slide upon said pipe and follow down with the globe until it reaches the position shown in Fig. 2, where it will be supported by the coupling a. It will be seen that when the hood is in the position shown in Fig. 2 the mantles are entirely protected from destruction by the wind or any other cause. When the globe is again placed on the lamp, the projections el upon the hood will engage the top of the globe, and the said hood will be pushed up with the globe until the position shown in Fig. 1 is reached. When the hood is in the position shown in Fig. 1, it acts as an inner casing, which protects the outer casing from becoming highly heated, and the heat-radiating surface of the lamp is thereby reduced.

As the above-described lamps are extensively used out of doors, the advantage of this invention will be seen, as a slight wind is sufficient to destroy the mantles when the globe is removed unless protected in some way.

Having thus described my invention, I claim and desire to-secure by Letters Patent 1. The combination in a lamp, of a casing, acentral pipe,a burner having mantles, ahood, arms attached to said hood, a sleeve carrying said arms, said sleeve being slidably mounted upon said central pipe, projections upon the said hood, and a globe adapted to engage said projections and support said hood, substantially as described.

2. The combination in a lamp of the character described, of a casing, a central pipe supporting said casing, aburner having mantles, ahood carried by asleeve slidably mounted upon said central pipe, said hood consisting of a casing slightly conical in form, a globe to support said hood and to hold it within said first-mentioned casing to prevent overa globe to support said hood, substantially as heating of the latter, and means of allowing described. 1 said hood to incase the said mantles when said In testimony whereof I aifix my signature in globe is removed, substantially as described. presence of two witnesses.

adapted to slide upon said central pipe, and MAX SGHERMER.
